Novel high-efficiency negative pressure type smoke exhaust ventilator

Abstract

The invention provides a novel high-efficiency negative pressure type smoke exhaust ventilator, which comprises a smoke exhaust ventilator body, a compressed air jet, arranged below the smoke exhaustventilator body and used for generating negative pressure and exhausting oil fume, and an exhaust duct arranged above the smoke exhaust ventilator body; the compressed air jet is internally provided with an exhaust fan used for exhausting external clean air and a negative pressure generator used for generating negative pressure, and the negative pressure generator is internally provided with an oil fume opening into which the oil fume is allowed to flow, the negative pressure generator is communicated with the exhaust fan through an airway. In the actual use process, the negative pressure is generated by compressed air injection, the smoke is sucked away and discharged out, exhaust fan blades are not arranged in the passage of smoke inhalation and exhalation, fan attachments are not neededto be cleaned and eliminated frequently, the manpower and material resource are both saved, and the environmental cleaning can be effectively ensured, the adsorption effect of the negative pressure is good, the oil fume is better exhausted and the efficiency is high. The novel high-efficiency negative pressure type smoke exhaust ventilator provided by the invention is reasonable in structural design, and is suitable for large-scale popularization and application.

Description

[technical field] [0001] The invention relates to the technical field of range hood products, in particular to a negative-pressure high-efficiency novel range hood free from oil and smoke contamination and without an exhaust fan. [Background technique] [0002] In recent years, range hood products have been rapidly developed and improved. Generally, range hoods have exhaust fans. During actual use, the blades of the range hood exhaust fans will be immersed in the smoke. This design The blades of the exhaust fan of the range hood will be polluted and adsorbed by oil fume during use, and need to be cleaned and removed in various ways, resulting in a large cleaning cost and a lot of inconvenience to actual use. [0003] With the continuous improvement of people's quality of life, people's requirements for humanization and practicability of products are getting higher and higher. For range hood products, the cleanliness during use and the impact on the surrounding air environmen...
